there s a programme on Sky Arts at the moment called ~~"The Beat is the Law" , about the 90 s Sheffield music scene,which is more or less the Fon story...with interviews with a lot of the Fon gang, a few 808 mentionsfilm made in 2010

That's the one - as I say, dunno if it has anything about FON on there, but it's apparently a very good documentary on the Sheffield music scene regardless (Cabaret Voltaire, Human League, Heaven 17, etc).
